Adding New Modules

1 A) To power down the control unit, pull out the main circuit breaker.

On a PARTNER Plus 220V system, move the on/off switch to the “off” position (“O”).

B) To remove the cover, place one hand on the

		handle on the bottom front of the cover and
		place your other hand on the top of the cover.
	C)	Gently pull the cover up from the bottom and tilt
		it towards the top until it detaches from the
2		backplane.
	A)	Before you insert the new module, make sure that
		all 400 (or 200) modules are installed to the
		right of all 206 modules. Also, remember to
		hold down the locking tab and to align the
		dovetail guides on the sides of the modules
		as you insert the new module.
	B)	Push the module slowly but firmly until it locks
		into place with two snaps, and is attached to
		the rear of the backplane and held in place by
		the locking tab on the bottom of the slot. Do
		not force the module. If it does not insert
		easily, remove the module, clear any
3		obstruction, and reinsert.
	A)	See “Connecting Lines and Extensions” for
		instructions on connecting line and/or
		extension jack cords to the new module.
	B) To power up the control unit, push in the main
		circuit breaker.
		On a PARTNER Plus 220V system, move the
		on/off switch to the “on” position (“l”).
4	Check all green lights on the fronts of the modules. If
	all the lights are lit, installation is complete; otherwise:

A) If a single light is out, power down the control unit, reseat the module, then power up the control unit.

If multiple lights are out, power down the control unit, reseat the first leftmost module that has a light out, then power up the control unit.

B) If the lights are still out, call the appropriate support telephone number as instructed on the inside front cover.
